GMN has expanded its range of sealed high-precision spindle ball bearings of precision class P4+ to include new sizes. GMN showcases a selection of models that are offered in two versions: S—for high speeds—and SM—for very high speeds. They are available in the 60xx and 619xx series. The 60xx models come in bearing sizes with bore diameters ranging from 17 to 50 mm, as well as 90 mm. For the 619xx variants, bearing sizes with bore diameters between 30 and 55 mm are available. Particularly in applications that place great demands on speed and load capacity, these new products are being used.

Also on display at the stand is a new freewheel, which can be used in bicycles, among other applications. While most designs require a spring for power transmission, this patented pending innovation operates without this component. Its function is integrated thanks to a springy cage geometry. As a result, the new freewheel is lighter, more efficient, and more reliable. Moreover, it can be manufactured more quickly and inexpensively with fewer components.
